Parcelable 序列化对象传递数据 以及传递集合demo

序列化的Parcelable
之前一直传递的都是些int类型String类型等等
就算传递集合传的一般也是

ArrayList<String>

或者 一个数组这种类型的很少传递一个

ArrayList<Object> 

这样的类型(注意object也得是一个序列化之后的对象)今天需求碰到了。网上看看别人写的都特别复杂。看起来有点蛋疼，所以看了下方法，写了如下demo，希望有些帮助吧，同时自己也记下，
注意 dest.writeList(val)这个写法的话 如果下边是readTypedList，那么会出现一个运行时异常，比较蛋疼

如下报错，应该就是对应关系搞错了。
